A Hazard of Hearts (1987) is a 1987 made-for-television romantic drama film starring Helena Bonham Carter in one of her first major roles. It is based on a 1949 novel by Barbara Cartland.
It was intended to be the first in a series of Barbara Cartland adaptations by producer Albert Fennell for CBS. He had optioned the novels 10 years earlier and tried unsuccessfully to get finance. His option lapsed and producer Ed Friendly made The Flame Is Love (1979) for NBC, which Cartland did not enjoy ("it was frightfully badly cast"). She was involved in A Hazard of Hearts (1987) from the beginning."
